You are if you're trying to remove the injectors from the manifold, there's no need. Simply remove upper part of manifold (plenum chamber), remove inlet manifold bolts and remove manifold complete with injection gear. Get a GOOD 6-point hex (not bi-hex) socket (16mm) for the head bolts and be careful with the rear outers, they are awkward in-situ. If the head bolts are the flanged type (integral washer) then they are stretch bolts and must be replaced. I always fit either the earlier non-stretch type or studs. Badger.
A bigger hammer probably ;)

Have to say that most of them will be 5/8" bolts, not 16mm. 16mm will fit but not as well as 5/8"
I rather imagine that the Thor engine got updated, but I wouldn't bet. all the earlier V8s I've seen use UNC or UNF bolts.
5/8 af 6-point sockets are pretty scarce in my experience Austin, 16mm is a perfect fit, hence why I quoted that size. BTW, all metric headed bolts that screw into the heads or block on a thor engine are still UNC threads!!! Badger.

hehe. 16mm is bigger than 5/8", but on a single hex you'll get away wit it as the difference is not too much, about 4 thou or so.
I've got a set of imperial a/f impact sockets, although I've had 'em some time.
I you need an odd proper AF true hex socket
Yep, and the tolerance on *most* modern spanners/sockets is probably a lot more than 0.004". I've been rebuilding V8 engines for over 15 years now, and I've rounded off head bolts whilst trying to undo them with the correct imperial socket (bi-hex, admittedly), but the 16mm hex has ALWAYS got them undone for me without any issues.

Badger uttered summat worrerz funny about:
At the risk of showing my arse and not having had the pleasure of many hex bolts could someone please explain the difference between bi-hex and single hex..... I've now got a smutty vision ;-)

Single hex sockets are just that Lee, a single hexagonal (6-sided) socket that fits a hexagonal shaped nut. Bi-hex is two hexagons superimposed with a 30 degree twist, to give a
12-pointed shape, the shape of most normal sockets. Bi-hex bolts (commonly used in the aviation industry) are the same, basically a 12-pointed nut. Badger.Badger uttered summat worrerz funny about:
Cheers! I suspected it would be painfully simple but as usual my mind has over complicated it :-)

like those buggers on the later LR calipers. Only thing I have against 'em is the fact that they reduce the size considerably compared to a normal hex-head bolt. They're not as bad as those ones with a reduced-size hex head, though, which are an abomination.
oh, and BTW - you can get small spark plug sockets in single-hex and 5/8", and being deep ones they're well-suited to V8 head bolts. You need a decent quality one though, not rubbish.

ISTR that bolt is 27mm, same as the later wheelnuts.
27mm A/F diesel injector socket fits it.
The 6 point ones are more expensive though. I think all the stuff i have (either inherited or from halfords/MM) is 12 point.

Just thought. I'm talking about a 300TDi, not a 200.
Austin did you ever come across those clever sockets described as edge drive they seem to have disappeared now though I googled and the US delaers still sell them under the SK SureGrip label. I think the idea was the flat of the hex was slightly curved towards the corner avoiding the rounding off you get on old rusty bolts not that landies are prone to them of course I did buy a few but I suspect that some time in the last 30 some years they may have evaporated.

the 6-sided ones don't do anything that a single-hex doesn't, though. The ideal socket would have a cam mechanism that closed the sides in against the hex before it started to turn, and pressed harder inwards against the hex the more torque you applied. Can't see how you'd make it though. Bit like those cunning spanners you can get which fit a range of nuts.
Most Koken sockets are designed like that as are all the Snap-On Flank Drive sockets and spanners.
